SPECIFICATION forming part of Letters Patent No. 464,680, dated December8, 1891.

Application filed August 23, 1890. Serial No. 363,304. (No model.)

To ctZZ whom it may concern.-

Be it known that I, CARL RICHARD SUND- STROM, a citizen of the UnitedStates, residing at Lindsborg, in the county of McPherson and State ofKansas, haveinvented certain newand useful Improvements in\Vind-lVheels; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification..

My invention relates to certain new and useful improvements inwind-wheels.

The object of the invention is to obtain a device of the characterdescribed which will regulate its speed according to the velocity of thewind, which can be easily started and stopped, and which will bestrongand durable.

To the accomplish ment,of the above the invention consists in certainnovel parts and combination of parts, as will hereinafter be fullydescribed and specifically claimed, reference being had to theaccompanying drawings, in which- Figure 1 represents a front elevationof my improved wind-wheel; Fig. 2, a side View, partly in section; Fig.3, a top plan view of the operative parts; Fig. 4., an enlarged detailof the lower end pieces of the fans, and Fig. 5 a detail of the frame towhich I attach my piston-rod.

In the drawings, A represents an ordinary tower provided with across-beam A, on which is mounted a hollow shaft or piping B, whichextends to a suitable height above the tower.

Mounted upon one end of the shaft or pipe B is the main frame of themill B, such frame being mounted upon the shaft by means of a platefastened to the under side of the frame, and formed in such a manner asto fit upon the end of the pipe and permit the main frame to revolvethereon, the plate being also provided with an opening a to permit ofthe passage therethrough of a piston-rod, as will be hereinafterdescribed.

Secured to main frame B atdiiferent points are four or more brace-rodsb, which extend downwardly and are connected to a collar 0, looselymounted on the pipe or shaft B, and adapted to revolve thereon. The mainframe on its inner end with a crank or gear-wheel E.

Outside of the main frame and connected to such frame by means of rods 6is a frame or cross-piece G. The rods 6 extend through the grooves orchannels the entire length of the main frame as shown at f, Fig. 3, andare not secured at their inner ends, this arrangement permitting saidcross-piece to be moved backward or forward.

The cross-piece G is provided with suitable bearings g, in which ismounted a hollow shaft H, through which runs the wheel-shaft D beforereferred to. Mounted on this shaft H is a wheel or disk H, which isprovided with a series of forked arms 7t, for the purpose hereinafterdescribed.

J represents a hub mounted on the outer end of the wheel-shaft D andrigidly secured thereto. Secured to this hub are rods 1, these rodsserving as supporters for the fans K, which consist of the frame 2" andlower end pieces which frames may be covered with any suitable material.These lower end pieces 7; are formed with a curved extension Z, which isadapted to run in the forked arms 71. hereinbefore referred to, thelower end piece 7c of each fan being provided with holes to accommodatethe rods 1', which are loosely mounted therein, thus allowing the fansto revolve thereon.

The arrangement of the parts above described is such that when the frameG is moved backward or forward it will carry with it the Wheel or diskH, and by means of the forked arms h, in engagement with the extensionZ, the fans K will be turned to a greater or less distance.

Between the fans K are mounted fans K, which are constructed in asimilar manner to the fans K, except that they do not extend down beyondthe collar m and into engagement with the forked arms of the wheel ordisk H. The fans K K are connected by a series of wires n, so that anymovements of the fans K will cause a similar movement of the fans K.

Near the end of the main frame is an upright or vertical arm M, whichextends to a suitable height above the wind-wheel, and

which is provided at its upper end with a wing or sail M. This rod isbifurcated or fork-shaped at its lower end, one arm of such fork beingsecured to each side of the main frame, as shown at 0, Fig. 3, in such amanner as to permit the arm M to be rocked to either side of itsvertical position. Secured to each arm of this fork is a rod or brace p,which extends forward and is connected to the movable cross-piece G. Bythis means it will be seen that when the arm M is moved from itsverticalposition in either direction it will move the frame G backwardor forward and with it the wheel or disk II, causing the tilting of thefans in the manner hereinbefore described.

Connected to the arm M at the point q is a rope q or cord,which extendsdownwardly to and over the pulley 0, located on the sail Q, the ropepassing from thence to and around a pulley R, located on the main frameand inside of piping B to within reach of the ground, the object of sucharrangement being to tilt the arm M and thereby turn the fans until theyare edge to the wind, thus stopping the wheel.

At a point r on the arm M is secured a cord or chain 0*, which runs toand over a pulley .9, located on a frame S, hereinafter to bedescribed,thence down through the main frame and down outside of theshaft to within a short distance above the top of the tower, where it isconnected with a weight 'l sufficiently heavy to return the arm M to itsvertical position when the rope q is released, and to hold it in such aposition during an ordinary wind.

Behind the crank or gear-wheel E and in front of the arm M is secured inthe main frame an upright frame S, which consists of the upright piecest and cross-pieces t.

Arranged to move up and down in grooves a (shown in dotted lines in Fig.5) is a crosspiece V, to which is secured the piston-rod V, whichextends down through the opening a, in the main frame, and thencethrough the pipe or shaft B, and is connected with p um p or otherdesired mechanism. A piston-rod X, connected with the crank i ofcrank-wheel E, is also pivoted to this cross-piece, the arrangementbeing such that when the crank-wheel is revolved by the turning of thewind-wheel it will cause the cross-piece Vto move up and down, carryingwith it the piston rod V, thereby furnishing the required power.

The operation of the parts is as follows: \Vhen the arm M is in avertical position, the fans will be at such an angle as to receive thefull force of the wind. The velocity of the wind becoming greater, thearm M will be forced from a vertical position, turning the fans at suchan angle that they. will not receive its full force, the weight Tpreventing the arm from being inclined too great a distance. Thus itwill be seen that the greater the velocity of the wind the less force itwill exert on the fans, the speed of the wheel being thus kept at auniform rate. Should the velocity of the wind become too great, the fanswill, by means of said arm, be turned with their edges directly towardthe wind, stopping the wheel entirelyand lessening the danger of itsbecoming damaged. Then it is desired to stop the wheel, it can be doneby means of the rope g, which, by being operated, will pull the arm fromits vertical position, thereby stopping the wheel, the weight Treturning it to an upright position as soon as the rope is released. Theweight 1 will also bring the parts into an operative position as thevelocity of the wind becomes less.

By the construction and arrangements of the parts as above describeditwill be seen that I obtain a wind-wheel which shall run at a uniformspeed, which can be easily stopped and started, and which will be lightand durable.

I am aware that prior to my invention the blades of windmills have beenpivot-ed and have been moved by a sail, the position of which isdetermined by the strength of the wind, the required motion beingimparted to the said sails by means of cranks secured thereto and havinga pivotal connection with pitmen actuated by the sail, and I do nottherefore claim such a construction; but

\Vhat I do claim is- In a wind-wheel, the combination, with awheel-shaft having a hub J upon the end thereof, of blades K centrallypivoted to the said hub, and having curved spring-arms on their baseprojecting toward the rear, of a disk H, mounted upon the saidwheel-shaft and revolving therewith, split pins IL', projecting from thesaid disk and engaging the said curved arms, and a pivoted governor vaneor sail M, adapted to cause a forward or rearward motion of the saiddisk II, whereby the pins h thereon will be caused to slide upon thesaid arms, as described.

In testimonywhereof Iaflix mysignature in presence of two witnesses.
